15C503 - Walter Coolcut 5-Inch Resin Fiber Disc 36 Grit

General Purpose Aluminum Oxide Sanding Disc

The Walter Coolcut™ 15C503 is a high-performance 5-inch resin fiber sanding disc engineered for industrial metalworking environments. Designed with premium aluminum oxide grains, this abrasive disc delivers consistent and aggressive stock removal, making it an essential consumable for fabrication shops, maintenance departments, and manufacturing facilities. The 36-grit composition is specifically formulated for heavy-duty applications, allowing operators to efficiently remove welds, blend surfaces, and perform rough shaping on steel components.

One of the defining characteristics of the Coolcut series is its ability to maintain a cool cutting action. This feature helps minimize heat accumulation on the workpiece, reducing the risk of warping or discoloration, which is critical when preparing surfaces for subsequent finishing steps. The disc features a standard 7/8-inch arbor, ensuring compatibility with a wide range of angle grinders and backing pads commonly used in the industry.

Sold in packs of 25, the 15C503 offers excellent value for high-volume operations. It serves as a reliable, general-purpose solution for steel applications where cost-efficiency and consistent performance are paramount. Whether used for beveling, deburring, or leveling welds, the Walter Coolcut disc provides the durability required to keep production lines moving smoothly.
